Improved egg-beater



'ii/'wi jf @W3/1 MFH ERS, FHOTO-LITHOGRAFHER. WASHINGTON D C UNITED STATES DAVID SHIVE, OF PHILADELPHIA, PENNSYLVANIA;

IMPROVED GGPBETER.

Specification forming part of Letters Patent No. 36,030, dated July 29. 1862.

To all whom #may concern.-

Be it known that I, DAVID SIIIvE, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Muddlers or Egg-Beaters; and I do hereby declare that the following is a full, clear, and'exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l represents a central longitudinal r section of the improved implement, and Fig.

2 a sectional plan view of the same below the line m of Fig. 1.

My invention relates to those devices intended for beating up eggs or mixing beverages, which are provided with two distinct agitators arranged to rotate, the one within the other; and it consists in the employment of a pair of slender cylinders or rolls arranged parallel with each other in a suitable frame and in connection with the said agitators, substantially as hereinafter described, so that the usual alternating rotary motions of the agitators may be effected by simply rolling or rubbing the cylinders transversely between ones hands.

In the drawings, A represents the frame; B B', the cylinders; O, the outer agitator; D, theinner agitator; E, aspindle or stem which carries the inner agitator; F, the stem or tubular shaft of the outer agitator; and G G', a pair of gear-wheels, whereby the rotary motion of the outer agitator is effected.

Theframe A consists of a piece of metal attened and bent to a right angle at each end, so as to adapt it to receive between the said ends the two cylinders B B', which in Ithis instance are made of hard wood, and each about three-eighths of an inch in diameter, and four inches long, more or less.

The agitator O is made of pieces of wire, 1 1, bent into the usual form and their upper ends soldered fast around the lower end of the tubular shaft F,while their lower ends are secured to a disk, h, which is perforated at its center.

The agitator D is similar in form though smaller than the agitator O, and has its wires 2 2 fastened by each of their ends to the stem E. The upper end of the saidstem E of the agitatorl) is passed up through the frame A and cylinder B, and secured so as to remain fixed in the latter and serve also as its axis of motion in the frame A.

The Y hollow shaft of the agitator C surrounds shaft E, and its upper end abuts against the lower end of frame A, while the lower end of shaft E passes through the hole in disk h, and has a flange or nut fixed thereon, so as to serve the purpose of keeping the said agitator in place, and at the same time allow it to have a free rotary motion upon the said shaft E.

rIhe upper end of the hollow shaft F has the pinion G fixed upon it, so as to gear with the pinion G', which is fixed on the lower end of axis i of the cylinder B', the latter being arranged to rotate in the frame A in a position parallel with and at a short distance from the cylinder B, substantially as seen in the drawings.

In the operation of this improved implement, it will be evident that if it be held by its cylinders B B' between ones hands, and an alternately backward and forward motion given to the latter, corresponding rotary motions will be given to the said cylinders, and consequently that alternating rotary motions in opposite directions to each other will be given to the agitators O and D, thus dispensing with the cumbrous fixtures and crank heretofore required to support and operate the agitators O and D, and effecting in a more appropriate, simple, and facile Inanner the motions required. The implement, being light and handy, is therefore also admirably appropriate to the purpose of mixing beverages in hotels and for family use as an eggbeater.

In construction, the cylinder B, shaft E, and frame A may be fixed immovably together, so that the outer agitator, O, only will rotate; but the free rotary motions of both the agitators O and D, as described, render the implement more eective either as amuddler or egg-beater, and add nothing to the cost of construction.

Having thus fully described my improved4 muddler or egg-beater and pointed out its utility, what I claim as new therein of my invention, and desire to secure by Letters Patent, is

Operating the agitators C and D, or their equivalents, by means of cylinders B B', arranged to be rolled or rubbed together between ones hands, substantially in the manner described.
